CALVIN N. COLPITTS, OF BOSTOBLJEASSAGHUSETTS, ASSIGNOR T AMERICAN SHADEMACHINE COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MAINE.

CLOTH CUTTING AND FOLDING MACHINE.

To all whom it may concern:

Be it known that l, CALVIN N. COLPITTS, a citizen of the United States,and a resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented an lmprovement in Cloth Cutting and FoldingMachines, of which the following descriptlon, in connection with theaccompanying drawing, is a specification, like numerals on the drawingrepresenting like parts.

This invention relates to machines for cutting and folding cloth, andthe embodiment of the invention herein illustrated has been especiallydesigned for trimming to proper width material for window shades;cutting the trimmed shade material into any desired lengths; and rollingu the severed lengths. The machine herein illustrated is also providedwith means for folding the edges of the trimmed material to form horns,and other means for providing folding creases across the end of thematerial at the point where the shade is to be folded at the bottom.

I will first describe one embodiment of my invention, and then point outthe novel features thereof in the appended claims.

of the edge trimmer; Fig. 21 is a section on the line ec, Fig. 1.

The operative parts of the machine are sustained on stands 3, and aredriven by a main shaft 4 which is sustained at its ends in heads 5 and6. The head 5 is stationary, while the head 6, shown in Fig. 5, isarranged to be moved toward or from the stationary head 5. The heads 5and 6 carry the edge-trimming and edge-folding mechanism, and the objectin making the head 6 adjustable is so that said head may be adjustedproperly relative to the head 5 for cutting shade material to any width.The movable head 6 carries two rollers 7 which are sustained on bars 9that extend transversely of the frame. For adjusting the head 6, I haveprovided an adjusting screw 10 (see Fig. 9) which extends longitudinallyof the shaft 4 and occupies a longitudinal slot 11 formed therein. Thisadjusting screw 10 has a screw-threaded portion 12 which extends throughand has screw-threaded engagement with a nut 13 that also occupies aportion of the groove 11. This nut 13 is reduced at one end to form theshoulder 16 and the neck portion 1 1, see Figs. 9 and 12, which neckportion extends longitudinally of the screw 10 and through the hub ofthe head 6, said neck portion having the enlarged end 15 at its end,which overlies the hub of said head 6. Said head 6 is thus confinedbetween the shoulder 16 and the enlarged end 15 of the nut 13. Said nut13 is held from rotation by its non-circular shape, see Fig. 11, whichfits the non-circular shape of the groove 11, and therefore the turningof the screw 10 will move the nut longitudinally of the shaft withoutturning the nut relative to the shaft, and since the head 6 and the nutare com elled to move in unison, the rotation of t e screw will shiftthe head 6 transversely of the frame. As shown in Fig. 12, the neckportion 14 of the nut is of such shape as to permit the shaft to rotatefreely in the head 6, and this construction, therefore, permits the freerotation of the shaft but provides for shifting the head 6 transverselyof the frame.

The screw 10 may be turned in any suitable or usual way, and as oneconvenient way I have shown the end of the screw 10 as having a pinion17 thereon, see Fig. 9, which meshes with an internal gear 18 carried bya hub 19 that is loosely mounted on the shaft 4, said hub having ahandle 20 extending therefrom by which it may be turned. The end of thescrew 10 is shown as reduced in size at 21, and such reduced portion isjournaled in a cap 22 which is held to the end of the shaft 4 by meansof suitable screws 23 which are screw-threaded into the shaft 4. Thiscap not only provides a bearing for the end of the screw 10 but alsooperates to hold the hub 19 with the internal gear 18 thereon,

in lace on the shaft 4.

ituated between the two heads 5 and 6 are a plurality of supports 24which are curvedin .the arc of a circle. The lower ends of these suports are slidably sustained in a groove25formed in the cross pieceorbarf), see Fig. 5, while the upper ends thereof are received .in.agroove 26 :formed in a plate 27 that extends transversely across themachine. These supporting members 24 are for the ,purpose of supportingand sustaining the .shade material as it is drawn ;past or through theedge-trimming and folding devices, as will be presently described. Theyare .all flexibly .connected together .by means of links 28 and theonesadjacentthe-heads 5 and 6 are flexiblyconnected theretobysimilar'links. The result of this construction .is that as the head-6is moved transverselyof themachine, see Fig. 4, the supporting members24 ,are moved in the grooves .25, 26 and automatically distributethemselves in the space between the heads.

The vframe'supporting the machine is constructed with the transverselyextending member 30, which is adapted to be .placed against the-edgeof atable 31 from which the shade materialis drawn, and during theoperationof cutting and trimming the shade material, said .material is drawn fromthe table 31.0ver the member 30,lover the plate 27, and down over thesupporting members 24 to a positively-driven feed roller 32 from whichthe shade material is fed .into the .receiving pocket 34.

The shaft 4.has mounted thereon two feeding wheels 118, .onesituatedadjacent each head .5 and .6. The feeding :wheel adjacent the head 5 isfast on the shaft, lieing keyed thereto by a key 42, see Fig. .9, whilethe other feeding wheel is arranged .to be rotated by the shaft hut iscapalile of being adjusted longitudinally thereof with the-head 6. Forthis purpose said latter feeding wheel is splinedon the nut 13, andconfined thereon by the retaining block 207 so that as said nut isadjusted longitudinally of the shaft, said feeding wheel is carriedtherewith. These feeding wheels cooperate with the feeding roll 32 tofeed the material over the supports 24 and into the ,pocket34.Thefeed-roll'32 isdriven from the sh aft 4 ymeansof a gear 9.1 thereonwhich meshes with and .drives a gear 90 rigid with said roll, see Figs.4 and 5.

3.3. and330 (sec Fig.1).are;presserrolls which co-act with the :feedroll 32. The 1011.330 is mounted in a pivoted arm 33] which is hacked bya spring 332. The roll 33 eX- tends the length ofthe machine and issustained at its ends in pivoted arms 94 that are backed by springs 95,see Fig. 1, wherehy the presser roll 33 is yieldingly held against thefeed roll 32.

While the shade material is being drawn over the supporting memh ers 24by the feed roll, it is acted upon lay the edge-trimming mechanism andfolding mechanism, which will now be described.

There is an edge-trimming mechanism mounted on each of the heads 5.and6, and each mechanism comprises a positivelydriven rotary disk-cutter 35and a cooper-ating rotary cutter 36. The cutters 35 arecarri ed by l:rackets 37 sustained hy the head-s5 and 6, .and said cutters have rigidtherewith pinions 38 which mesh with idler pinicns 39 carried lay saidheads, and the idler pinions mesh with and are driven by gears 40 and 41mounted on the shaft 4, .see Figs. .1 and 9. The gear 40 is keyed. tothe shaft by means of a key 42, see 9 and 10, and the gear is keyed tothe shaft by the nut 13, see Figs. 9 and 11, said gear lJ-eing confinedl? tween thefeeding wheel 11S ,ano the head 5. Both of these gears must,therefore, rotate with the shaft 4, hut since the gear 41 is mounted onthe nut 13, said gear will he moved longitudinally of the shaft with thenut, and may, therefore, he adjusted. with the head 6. The rotation .ofthe shaft 4, therefore, will positively rotate hothcutters 35. The shaft4. is rotated by means of the handle 43, whichdspivotedon a stud44pmjecting from the frame 5, and has rigid with the huh thereon a gear46 which meshes with an-idler 47 also carried by the frame 5. The idler47 in turn meshes with a gear 48 which is keyed to the shaft 4.

The cutters 35, 36, are shear cutters, that is, theyoverlap eachother,as shown in Fig. 20,and operate to cut thegoods with a shear cut. Thecutters 35 each have associated therewitha roll 50 which is rigidlysecured to the cutter and with which theshade inaterial has contactas itis drawn past the out ters. Each cutter36 is sustained on a stud 5.1which is carried by the arm37 secured to the correspondinghead, and eachcutter 36 also has rigid therewith a roll .50 which is situatedover andcooperates withthe roll'50 of the cutter 35. Both the rolls 50 arepreferahly provided with roughened surfaces so as to increase thefrictional engagement hetween them and the shade material.

T hegearing for driving each cutter 3.5 is so proportioned that the roll50 for said cutter has a surface speed. equal to the speed of movementof the shade material, and since the roll 50 for each cutter 36 hasfrictional enga ement with the shade .material, as

shown in Fig. 20, it willfollow thateach cutter 36 will be rotated atthe same speed as the corresponding cutter 35. These two rolls 5O servetherefore both to hold the edge of the shade material in proper positionand to provide means for driving the top cutters 36. The rolls 56 forthe top cutters 36 are beveled on one edge, as at 500, thus forming anannular groove in which the cutters 35 may be received, as plainlyindicated in Fig. 20.

I have provided for varying the frictional engagement between the rolls50 and the cloth and also for adjusting the roll of the upper cutterstoward and from those of the lower cutters to accommodate differentthicknesses of cloth. This is accomplished in this embodiment by makingthat portion of each stud 51 which carries a cutter 36 slightlyeccentric, see Fig. 20, so that by turning the stud in the arm by meansof a handle extending rom the stud, the cutter 36 may be carried towardand from the other cutter.

53 is an arm pivoted to the arm 4-9 and carrying at its end a pin 54which bears against the end of the stud 51 and holds the latter inplace. The cutter 36 is held on the stud 5]) by a cotter pin or otherequivalent means.

Associated with each pair of edge-trimmers 35 and 36 are creasersadapted to form creases in the edge of the trimmed material, on the lineof which creases the material is to be folded. These creases eachcomprise creasing wheels 56 and 57, the wheels 57 being grooved and thewheels 56 being shaped to fit the grooves. Each wheel 57 is sustained ona stud 58 extending from the arm 49, see Fig. 4, and each stud has fastthereon a friction wheel 59 that is situated over the plate 68 and isadapted to rest on and be rotated by the cloth as the latter is drawnover said plate. Each creasing wheel 56 is mounted on an arm 60 which ispivoted to the head 5 at 61, and which is acted against by a spring 62that yieldingly holds said creasing wheel 56 against the cocperatingwheel 57. The spring 62 bears at one end against the head 5, and theother end against a screw 63 carried by the arm 60, by means of whichscrew the tension of the spring may be adjusted.

It is often desirable to make the creases which are formed by the wheels57, 56 at different distances from the edge of the trimmed material, andto permit this to be done, I have in the present embodiment of myinvention mounted the cutters 35, 36 so that they can be adjusted towardand from the creasing wheels. It will be noted that the creasing wheelsare mounted on the heads 5 and 6, while the cutters 35, 36 are carriedby the brackets 37. Each bracket 37 is adjustably sustained by its head,so that it with the cutters carried thereby can be moved toward and fromthe creasing wheels. While any suitable way of thus adjustably mountingthe brackets may be employed, 1 have herein shown each bracket assustained by pins 501 extending from the head and as having journaledtherein an adjusting screw 502 which is screw-threaded into the head. Byturning the screw, tae brackets may be adjusted so that the materialwill be out at the desired distance from the crease.

Associated with each creasing mechanism is a folding device adapted tofold the trimmed edge of the material on the line of the crease. Eachfolding device comprises a curved folding finger 64 which is sustainedso by an arm 65 extending from the head 5 or 6 as the case may be. Oneend 66 of each folding finger is situated so that the cloth will passunder said finger, and the other end 67 of said finger is bent down andearned under the curved folding plate 68 which is carried by the head,so that as the cloth is drawn over said plate the creased edge is f ldedthereunder. A similar folding device is used on each of the heads 5 and6.

It will be noted that the folding plate 68 is curved, and this is adecided advantage, because the fold in the edge of the cloth is madewhile the cloth is resting against this curved folding plate. Because ofthis condition, the edge of the cloth can be folded over without causingany wrinkles or straining the cloth as could not be done if the foldingwere done while the cloth were straight.

When a sufficient length of material has been trimmed and folded, suchlength is cut off by a cutter which is adapted to move transversely ofthe material and longitudinally of the plate 27. This cutter ispreferably in the form of a disk cutter 70 which is mounted on acarriage 71 adapted for move ment longitudinally of the plate 27 andtransversely of the material. Suitable means are also provided forrapidly rotating this cutter 70 during the traveling movement of thecarriage. The carriage 71 is also preferably so constructed that duringits movement transversely of the material it operates to crease thematerial adjacent to the cut end thereof so as to facilitate the foldingof the hem at the bottom of the severed length of material. For thispurpose, the plate 27 is provided with ll-shaped tracks 72, 73, and thecarriage 71 has the grooved wheels 74, 75, that travel on said tracks,see Figs. 1 and 4.

The shape of the tracks 72, 73 and the wheels 74, 75 is such that as thecarriage moves over the shade material which over lies the tracks, thewheels and tracksform the requisite crease in the shade material.

The tracks 72, 73 and the plate 27 extend beyond the edge trimmingcutters, as shown in Fig. 4, so that when the carriage 71 is at theright hand end of its travel, Fig. 4, it does not interfere with thedrawing of the shade material from the table 31 over the plate27 and:down past the edge trimming and folding devices. When a sufficientlength of shade material has been drawn from the table31 then thecarriage 71 is moved upon its tracks transversely ofthe shade material,and during such movement the length of shade -material is cut off bythecutter and the crease for the hem in-the endof the shade materialzisformed by the wheels'74, 75.

While any suitable means for giving the carriage its movement may beemployed, 1 have herein illustrated an endless cable arrangement which Ifind to be convenient because it can be operated readily from one sideof the machine.

As illustrated, the carriage 71 has secured thereto one end of aflexible connection. 76, which flexible connection passes around adirection pulley 77 at one end of the frame and then extends to andaround a drum 78, see Fig. 15. Said carriage also has secured theretoanother flexible connection. 79 which extends around a direction pulley80 at the other side of the frame and. then extends to the drum 78, theconnections 76 and 79 being wound about the drum 78 in oppositedirections. The shaft of the drum 78 has a pinion 81 thereon whichmeshes with and is operated by a rack 82. This rack is connected at oneend to a sliding actuator 83 which is mounted to slide on ways 84, andwhich has extending therefrom a handle 85 by means of which it may bemanually operated.

When it is desired to move the carriage 71., the operator grasps thehandle 85 and slides the actuator 83 on the guides 84, said actuatorthrough the link 82 operating to turn-the drum 78 and to wind up one ofthe flexible connections while permitting the other to unwind. Thecarriage is thus given its reciprocating movement.

The size of the pinion 81 is relatively small compared with the size ofthe drum 78, and therefore a comparatively small stroke of the actuator83 is sufiicient to give the carriage its full movement in eitherdirection.

For rotating the cutter 70, I haveprovidedv a pinion 86 on the carriage71, which pinion is adapted to mesh with rack teeth 87 on the bottom ofthe transverse bar 88 by which the pulleys 77 and 80 are supported asplainly seen in Figs. 6 and 15. This pinion 86meshes with a pinion onthe shaft 750 carrying the cutter 70 and thus the cut ter is rotated asthe carriage ismoved. The edge of the cutter 70 is received in a groove89 formed in the plate 30, and by its rapid rotation it operates to cutthe goods during the'movement of the carriage.

As stated above, the feeding rolls 32, 33 arepositively drivenandoperate to feed the tenses trimmed length of shade material into thepocket 34.

For driving these feeding rollers, I have provided the roller 32 with agear 90 whichmeshes with andis'driven by a gear 91 fast on the shaft 4;and the roller 33 is also provided with a gear 92 which meshes with andis driven. by the gear 90. The roller 33 is preferably yieldinglymounted and for this purpose is carried by two arms 94 pivoted to theframe and is acted on by two springs 95 which tend toyieldinglyhold theroller 33 against the roller 32.

Situated adjacent the feed rollers 32 and 33 and in position to receivethe shade material therefrom is an open throat 96 (see Figs. 18 and 19)leading to the pocket 34. This throat is formed by the stationary guideplate 97 and the cooperating movable guide plates 98. The movable guideplate is carried by arms 99 which are curved, as shown in Fig. 1, andare provided with the stems 100 which are pivoted to the frame at 101.

Extending between the two arms 99 are two shafts 102 on each of which ismounted a plurality of friction rolls 103, the rolls on the two shafts102 preferably being staggered, as shown best in Fig. 4.

The two arms 99 support a rock shaft 104 which has rigidly extendingtherefrom arms 105 that carry a shaft 106 on which are rigidly mountedrolls 107. The rolls 103 and 107 form the periphery or bounding wall ofthe pocket 34, and all these rolls are positively driven. The functionof these rolls is to receive the shade material from the throat 96, andby positively acting on it to roll the length of shade material as itcomes into the pocket 34 up into a roll, as shown in Fig. 18. Forpositively driving these various feed rolls, I have shown the gear 90 asmeshing with and driving an idler gear 108 which in turn meshes with anddrives agear 109 loose on a stud carried by the frame, and said gear 109meshes with and drives a gear 290 which is loose on one of the shafts102. This gear 290 has a pawland-ratchet connection with a pulley 110which is fast to the said shaft 102, and said pulley is-belted to apulley 111 on the lower shaft 102 and is also belted to an idler 211 onthe rock shaft 104, said idler being in turn belted to a pulley 212 onthe shaft 106, as plainly seen in-Figs. 2 and 8. With this arran gementthe feed rolls on the shafts 102 and 106 are driven in the properdirection for rolling up the shade material in the pocket as the latteris fed thereinto. As the shade material is fed over the feeding wheels118, it is deflected by the deflecting block 220 into position to be fedbetween the feed rolls 32, 33, as seen plainly in Fig. 18, and from thelatter it is fed into the throat 96, the plates 97 and 98 being flaredat the opening of the throat to direct the edge of theshade materialthereinto.

After the length of shade material has been severed and has been fedinto and rolled up into the pocket 34, I have provided for opening saidpocket to permit the severed and trimmed length to be dischargedtherefrom.

As stated above the stems 100 of the arms 99 are pivoted to the frame at101, and connected to the extended ends of one of the stems is a link310 provided with a hooked end 311.

The shaft 104 has rigid therewith an arm 112 which carries a pin 229playing in a slot in the end of a link 113 which in turn is pivoted to aplate 114 that is adjustably secured to a bracket 115, which issustained by the frame ofthe machine. The handle 143 by which the shaft4 is operated carries a block 232 which is beveled on one side, as at233, see Fig. 2, and provided with an aperture 231, said block having ashank 230 which is sustained by ears 234 projecting from the handle 43and which is surrounded by a spring 235 which tends to keep the blockmaintained in the position shown in Fig. 2. The aperture 231 in saidblock is adapted to receive the hooked end 311 of the link 310 and whensaid hooked end is occupying the aperture, the turning of the handle 43backwardly will operate to draw the link 310 to the left and thus swingthe arms 99 into the position shown in Fig. 19. Y hile the arm isswinging into this position, the pin 229 carried by the arm 112 isbrought down against the end of the slot in the link 113 and duringcontinued swinging movement of the arms 99, the link 113 and arm 112serve to raise the arm 105 slightly. The result of this operation isthat the pocket becomes fully opened, as shown in Fig. 19, the plate 93being withdrawn entirely from beneath the plate 97, and the roll ofmaterial which has been rolled up in the pocket is permitted to dropout.

The block 232 is swiveled in the ears 234 to permit it to turn in theears as the handle is turned backwardly.

v hile the handle 43 is being turned forwardly for drawing the shadematerial past the cutters and folders, the link 310 is disengaged fromthe block 232 and therefore the pocket 34 remains in its closedcondition.

Whenever the length of shade material has been trimmed and cut and hasbeen rolled up in the pocket, then the hooked end 311 of the link 310 isplaced in the aperture 231 and the handle 43 moved backwardly thereby toopen the pocket as above stated and permit the rolled-up material to bedropped therefrom.

After a length of shade material has been severed from the untrimmedmaterial on the table 31 and said length has been fed into and rolled upin the pocket 34, as above described, it is necessary to draw the uncutand untrimmed material from the table 31 over the supports 24 and intoposition to be gripped by the feed rolls 32, 33. To ac complish this, Ihave provided a plurality of grippers which are arranged to be movedinto position to grip the edge of the uncut shade material and draw thelatter over the supports 24 and deliver such material to the feedrollers 32, 33. These grippers are mounted on the feeding wheels 118which are carried by the shaft 4, see Figs. 5, 16 and 17, one of saidwheels being keyed to the shaft by the key 42 and the other being keyedto the shaft by the nut 14. Each of the wheels has a pair of grippingjaws 119 and 120, see Figs. 5, 16 and 17. Each gripping aw 120 iscarried by an arm 121 which is loosely mounted on a stud 122 carried bythe wheel 118, each arm 121 having a tail 123 provided with alaterally-extending pin 124. Each jaw 119 is carried by an arm 125 whichis rigid with the shaft 122, and each shaft has extending therefrom anarm 126 which is acted on by a suitable spring 127.

A spring 123 is used for normally holding the j aws closed together.Each head 5 and 6 carries a pivotally-mounted pawl 129 in position to beengaged by the pin 124. The pawls 129 are so placed that when the shaft4 and feeding wheels rotate backwardly, see Fig. 1, or clockwise, seeFig. 5, the pins 124 come into engagement with the pawls at the timewhen the wheels are carried into position to engage the edge of theshade material on the plate 30, as shown in Fig. 16, and when said pinsstrike the pawls, the jaws are opened so that the edge of the shadematerial enters between the gripping jaws during the movement of thelatter, it being noted that the member 30 is concaved on its upper faceso that the inclined surface 345 directs the edge of the material mupwardly, as shown in Fig. 16, into position to be readily grasped bythe jaws. if hen the pins 124 pass off from the pawls 129, the grippersare closed together on the shade material by the springs 127, 123. W henthe edge of the uncut material on the table 31 has been thus gripped bythe grippers 119 and 120, the shaft 4 is rotated in the oppositedirection or clockwise, Figs. 1 and 16, and the grippers serve to drawthe material across the plate 27, past the edge trimming and foldingdevices and down into position to be fed between the rolls 32 and 33.

As the feeding wheels begin their feeding movement, the his 124 passabove the pawls 129, and since the latter are pivoted they yield to themovement of the pins and do not cause the gripper jaws to be opened.

To cause the gripper jaws to release the material at the proper time,the heats 5 and 6 are each provided with cams 130, see Fig. 5, which arein position to engage the pins 124 and open the gripper jaws when thelatter ,are substantially opposite the feed roll '32. After the edge ofthe material an passes between the-feed roll 82 and the feeding wheels118 and has been released by the grippers, furtherfeedmg movement thematerial s .accomplished by thecemhined action of said feedroll andfeeding Wheels, and the deflecting block 220, see Fig. 18, operates todeflect the edge .of the material between the feed rolls32 and 33.

Since the feeding wheels 118 carrying the grippers are mounted to rotatewith the shaft 4 it is necessary to turn the shaft 4 hackavardly tobring the grippers into position to grip theedge of the material on .thetalzle 31, andas soon as thegrippershave engaged the material the shaftis turned forwardly again by the. handle 43, thus drawing the shade,materialover the support 24.

It is during the hack-ward turning .movement of the handle 43 necessaryto give the grippers their backward movement that the link 310 isoperated on to open the pocket 34, as above described.

lhave also provideda gage by which predetermined lengthsof shadematerial may .he drawn from the tahle 3.1 at each operation of themachine. lhe,gage may he adjusted so that any desired length may hedrawn from the table at each operation, and said gage is so arrangedthat the shaft 4 and con-- sequently the feeding means will hepositively arrested when the desired length has heenso .drawn from thetalile.

.As ,herein illustrated the head .5 has rigid therewith .a gage ring 140provided with a plurality ofapertures 141. Loosely mounted .on astud 142carried by the head 5 (see Fig. 14) is a gagearm 143 carrying at its enda pm 144 which canhe entered into any-one of the apertures 141 dependingon the position of thearm 143.

The arm 143 carries a stop device 145 whichis mounted on an arm 1 46pivoted to the arm 143. Loosely mounted on the stud 142 is a gear 147which meshes with and is driven by a gear .148 loosely mounted on theshaft 4,see Fig. 9.

The gear 148 is normally locked to the gear 48 by means of thespring-pressed pin 149 which is slidahly mounted in thegear 48 andprojects through the latter into a notch in the gear 148. Said pin 149has projecting therefroman arm 150 which works in a slot 151 in the hubof the gear 48, as seen in Figs. 9 and 13.

T he gear 147 is provided with the large or stop tooth 152 which isadapted to engage the stop 145 as thegear 147 is rotated. The gage ring1 is graduated, as shown in Fig. 1,- and the arm 143 is provided with apointer 155. When the parts are in the normal position the large tooth152 of the gear 147 rests against the hub of the gear 148. As

the cutter operates.

so that -.the shaft .4 is turned -.to draw the-shade material from thetahle 31, the gear 147 is turned .in the direction of the arrow, Fig. 1,and this operation may continue until the stop tooth 152 engages thestep 145 when further movement of the shaft 4 will he arrested. Thedistance that the gear 147 can he thus turned before it is arrested,depends on the position of the gage arm 143 and this may he set so thatany desired length of-material will be drawn from the table at eachoperation.

In the operation of the machine, it is necessary after a length has beensevered lay the cutter 7 O to feed said lengthcompletely into the pocket34 before bringing the grippers into position to feed a fresh lengthonto the supports 24, and, therefore, 1 provide for releasing the step145 from the stop tooth 152 hy the movement of the carriage 71 For thispurpose the step 145 has pivoted thereto a pawl 160 which is acted on byasuitahle spring 161,

see Fig. 3, and which pawl is normally held against the step 162 by saidspring.

The pawl 160 in its normal position overlaps slightly the shoulder 163of the-stop 145 i when the stop tooth 152 is hrought into engagementwith the shoulder the pawl 160 is swung to the left slightly. Y

The arm 146 has connected to one end thereof a flexible connection 165which extends through aneye 1 66 carried by the arm 143 in line withthestud 142 and which extends thence to a lever 167, see Fig. 14,pivoted to the plate 30. The lever has pivotally connected thereto a pin168 which extends through an aperture in the plate 27 and which is inposition to be engaged by the rolls 169 mounted on the carriage 71. Assaid carriage is moved over the track for cutting a lengthof shadematerial and creasing the edge of the latter, the roll 169 depresses thepin 168 thereby drawing on the connection 165 and raising the stop '145out of engagement with the stop tooth 152. As soon as the stop is thusraised out of engagement with the tooth the spring 161 returns the pawl160 to normal position so that when the roll is passed off from the pin168 and the arm 146 returns to its normal position, the stop is held outof engagement with the stop tooth, as shown in Fig. 3, and the gear 147is free to be further rotated. After the carriage has been moved acrossthe machine thereby to cut a length of shade material and the stop 145has thus been released from the stop tooth 152, the operator maycontinue the rotation of the handle 43 and the shaft 4 until the severedlength of shade material is completely fed into the pocket 34. Thecarriage 71 is arranged so that it may he moved across the table in onedirection to sever the first length and then brought back across thetable in a reverse direction to sever the neXt length, etc.

I have also provided for returning the gear 147 to its initial positionat the time that the shaft 4 is reversed to bring the grippers intoposition to engage the length of material on the table 31. To accomplishthis, the gear 147 has connected thereto one end of a spring 170, theother end of which is fast to the head 5, said spring being arranged sothat as the gear is rotated in the direction of the arrow, Fig. 1, thespring is wound up. The head 5 also carries a pivoted cam 171, see Fig.13, which is adapted to engage the arm 150 when the shaft 4 and the gear48 are retated backwardly thereby to withdraw the pin 149 from the gear148. The cam 171 is so arranged that when the shaft 4 is turnedforwardly the arm 150 will pass in behind said cam and force the latteroutwardly against the action of the spring 175. W hen, however, theshaft is turned backwardly the point of the cam enters between the arm150 and the gear 48 thereby withdrawing the pin 149. As soon as the pin149 is thus withdrawn sufliciently to unlock the gear 148 from the gear48, the spring 170 will automatically return the gear 147 to its initialposition.

The operation of the device will be readily understood from the abovedescription, but may be briefly summarized as follows: The gage arm 143is first set according to the length into which it is desired to cut theshade material, and the uncut shade material is placed on the table 31.The edge of the shade material is then passed under the spring-pressedroll 190 and brought into such position on the upper face of the meniber30 that the edge of the material projects slightly beyond the surface345 and into position to be gripped by the jaws 119 and 120, as shown inFig. 16. The handle 43 is then turned backwardly thereby causing thegrippers to be carried into position to grip the edge of the material,said grippers being automatically opened at the proper time by thepivoted cams 129. When the grippers have engaged the edge of the materiathe handle 43 is turned forwardly again thereby feeding said materialover the plate 27 and past the edge-trimming and edgefolding mechanism.The grippers automatically release the material at the proper time, andsaid material is deflected between the feed rollers 32 and 33 by thedeflecting block 220, and is fed into the pocket '34 where it is rolledup. The rotation of the shaft 4 also operates to positively drive theedge-trimming cutters 35, 36, as above described, and as the materialpasses through said cutters it passes between the creasers 56, 57, whichcrease it on the line where it is to be folded for making the side hem.From the creasers the material passes under the folding finger 67 whichfolds the creased edge around the plate 68, as above described. v'i henthe proper amount of shade material has been thus drawn from the table31, fur ther rotation of the shaft 4 is stopped by engagement of thestop tooth 152 with the stop 145 and the operator then manipulates theactuator 83 thereby to cause the carriage 71 to traverse the tracks 72,73 and thereby sever the lengths of shade material and at the same timecrease the latter.

The movement of the carriage operates to release the stop 145, as abovedescribed, so that the handle 43 and shaft 4 may be rotated furtherthereby to draw the severed length of material completely into thepocket. The handle 43 is then turned backwardly to cause the grippers toengage the edge of the material still remaining on the table P1 therebyto draw a fresh length through the edgetrimming devices, edge-creasingand edge-folding devices and into the pocket 34, and during suchbackward movement of the iandle, the said pocket 34 is opened by theengagement of the spring pressed block 232 "with the hook 2311 therebyto permit the rolled-up lengths of shade material within the pocket tobe discharged therefrom nd at the same time the gear 148 is disconnectedfrom the gear 48 by the cam 171 and the gear 147 is returned to itsinitial position. These operations are then repeated.

it will be noted that there is one track 72 and a plurality of paralleltracks 7 3. The object in making a plurality of tracks 73 is for makingthe two creases at the bottom edge of the material different distancesapart depending upon the width desired for the hem. The wheel 75 whichoperates on the track 73 is slidably mounted on its journal 750 so thatit may be set to travel over any one of the tracks 73 as desired.
